Genes affected

RPH3A (HGNC:17056): (rabphilin 3A) The protein encoded by this gene is thought to be an effector for RAB3A, which is a small G protein that acts in the late stages of neurotransmitter exocytosis. The encoded protein may be involved in neurotransmitter release and synaptic vesicle traffic. [provided by RefSeq, Dec 2016]

The c.134G>A (p.R45K) alteration is located in exon 5 (coding exon 3) of the RPH3A gene. This alteration results from a G to A substitution at nucleotide position 134, causing the arginine (R) at amino acid position 45 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
